The value of Delta_(0) " for " [Ti(H_(2)O)_(6)]^(3+) is found to be 240 kJ mol^(-1) then predict the colour of the complex using the following table . (h=6xx10^(-34)J-sec,N_(A)=6xx10^(23)c=3xx10^(8) m//sec)

The first ionization energy of Na is 495.9 kJ mol^(-1) . What is the longest wavelength of light that could remove an electron from a Na-atom?

The energy difference between two electronic states is 399.1 kJ mol^(-1) . Calculate the wavelength and frequency of light emitted when an electron drops from a higher to a lower state. (Planck's constant, h = 3.98 xx 10^(-13) kJ mol^(-1)) .

Splitting energy (Delta_(0)) can usually be measured form the absorption spectra of the complex ions. In simple cases when light is absorbed by a complex ion, an electron in one of the lower energy orbitals is excited to one of the higher energy orbital. The energy corresponding to the frequency of absorbed light is equal to Delta_(0) . If value of Delta_(0) for the complex is in visible region, the complex is coloured and the value of Delta_(0) lies in ultraviolet or infrared region, the complex is colourless. For octahedral complexes, the cyrstal field stabilisation energy is given by CFSE= +[-0.4t_(2g)N+0.6e_(g)N_(1)]Delta_(0) Where N and N_(1) are number of electrons in t_(2g)" and "e_(g) orbitals respectively. The value of CFSE can be used for the correction of the experimental values of heats of hydration of divalent can be obtained by substracting the calculated CFSE values form the experimental values. The value of crystal field splitting (Delta_(0)) for [Ti(H_(2)O)_(6)^(3+) is 243 kj mol^(-1) . The crystal field stabilisation energy (CFSE) in this complex is : (in kj mol^(-1) )
